Metal-filled 3D filaments are composite materials that blend plastic with fine metal powders, offering the strength and aesthetic appeal of metal. Ideal for creating parts with a metallic look and feel, these filaments provide enhanced rigidity, weight, and durability. They print at a temperature range of 374°F to 464°F (190°-240°C) and require a hardened nozzle due to their abrasive nature. Metal-filled filaments are perfect for creating functional prototypes, decorative items, and mechanical parts with a metallic finish, delivering a unique combination of strength and visual appeal.
